Description

Description générale

Sodium cyanide is colorless sodium salt and its crystals belong to the cubic crystal system. Its aqueous solutions are strongly basic due to the presence of cyanide ion. It can be synthesized by reacting sodium hydroxide with hydrogen cyanide. Sodium cyanide is a key precursor for the synthesis of various organic intermediates. It participates in the RuCl₃-mediated oxidative cyanation of tertiary amines.

Application

Sodium cyanide may be employed for the synthesis of the following compounds:

• α-amino acids
• Prussian blue (cyanide pigment)
• nitriles, via reaction with primary and secondary chlorides
